Find the measures of the interior angles of the triangle.

Answers

Answer:

A=45

B=110

Step-by-step explanation:

Interior angles of a triangle add up to 180.

So, do 180-25=155.

Then, 155-65=90.

90 divided by 2 is 45.

x=45 so B is 45+65, which is 110.

A blueprint of a house shows a wall that is 5 inches long. If the blue pretty strong to a scale of 1:60, what is the actual width of the wall in the house

Answers

Given:

A blueprint of a house shows a wall that is 5 inches long.

The blue pretty strong to a scale of 1:60.

To find:

The actual width of the wall in the house.

Solution:

The blue pretty strong to a scale of 1:60.

It means, the dimensions of blueprint to the actual house is 1:60.

Width of a wall in blue print = 5

Let the actual width of the wall in the house be x.

[tex]\dfrac{5}{x}=\dfrac{1}{60}[/tex]

[tex]5\times 60=1\times x[/tex]

[tex]300=x[/tex]

Therefore, the width of the wall in the house is 300 inches.

Of the 40 randomly chosen students surveyed, 27 are involved in extracurricular activities at school. There are 680 students at the school. Predict the number of students in the school who are involved in after-school activities. (Please answer the right answer and how you got the answer)

Answers

Answer:

It's around 459. So 460 if need to round

Step-by-step explanation:

So, 40 randomly chosen people do not represent  the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)

A flower shop ordered a shipment of red, blue, and white flowers. The ratio of red: blue: white flowers in the shipment is 3: 1: 2.There are 60 white flowers in the shipment. How many flowers are in the shipment.
A.120 flowers
B.180 flowers
C.240 flowers
D..360 flowers

Answers

Answer: A

Step-by-step explanation: this is to easy

The total number of flowers in shipment is 180.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

The ratio of flowers,

red: blue: white = 3:1:2

Let red flowers are 3x,

Red flowers are x,

and white flower are 2x.

Therefore, total number of flowers = 3x+x+2x = 6x

Given that,

The total number of white flowers = 60

⇒2x = 60

x = 30

Total number of flowers = 6x = 6×30 = 180

There are 180 flowers in the shipment.

1.Given the lines shown here, what are two possible equations for this system of equations
2.How many solutions does this system have?

Answers

Answer:

Two possible equations:

[tex]y = x + 1\\y = x - 5\\[/tex]

The system has 0 solution as parallel lines never cross each other.

Step-by-step explanation:

Considering the two lines are parallel, they both have the same slope.

let m be the slope of the two lines:

[tex]y = mx + y_{0}\\y=mx+y_{1}[/tex]

[tex]y_{0}, y_{1}[/tex] are the value on y axis where the two lines cross the axis.

Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.

Answer:

f(6) = -10

Step-by-step explanation:

Plug in 6 for x in the given equation:

f(6) = -2(6) + 2

Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:

First, multiply. Note that when you are multiplying one negative number and one positive number together, your answer will be negative:

f(6) = -2(6) + 2

f(6) = (-2 * 6) + 2

f(6) = (-12) + 2

Next, simplify. Subtract:

f(6) = -12 + 2

f(6) = -10

-10 is your answer when f(6).

Ariana is going to invest in an account paying an interest rate of 3.7% compounded monthly. How much would Ariana need to invest, to the nearest dollar, for the value of the account to reach $25,000 in 14 years?

Answers

Answer:

14905

Step-by-step explanation:

Use Calculator. Round to the nearest dollar

The amount of money that Ariana needs to invest today in order to reach $25,000 in 14 years is $14,913.

How much should Ariana invest today?

In order to determine the amount of money that Ariana should invest today, the present value of $25,000 has to be determined.

The formula that can be used to determine the present value is:

P = FV / (1 + r)^nm

Where:

FV = Future value P = Present value R = interest rate = 3.7% / 12 = 0.308%m = number of compounding = 12N = number of years

P = 25,000 / (1.00308)^(12 X 14) = $14,913
